This review of the impact of conventional combined orthodontic-surgical treatment (COST) and the surgery-first approach on oral health–related quality of life (OHRQoL)included 24 prospective studies showing an inital decrease tfollowed by an improvement in OHRQoL
This review looking at the optimal force magnitude for achieving orthodontic tooth movement included 12 studies suggesting there is weak to moderate evidence showing that forces ranging between 50 cN and 100 cN are optimal for the rate of orthodontic tooth movement.
This review assessing the predictability of clear aligners and treatment outcomes of clear aligner therapy compared with fixed appliance therapy included 7 small studies of limited quality.
This Cochrane review update evaluates whether topical fluoride reduces the proportion of orthodontic patients with new demineralised lesions (white spot lesions). In included 10 studies finding some low certainty evidence that some topical fluorides reduced white spot lesions.
This review evaluating the difference in stability between lower fixed retainers bonded on all six anterior teeth and those bonded only to the canines included 5 studies. Only 2 of the studies were RCTs with finding suggesting better outcomes with bonding to all anterior teeth but the quality of the evidence is low.
This review of the occurence of maloclusion in children/adolescents with Down syndrome included 11 studies and suggests a higher prevalence of malocclusion.
This review of self-applied topical fluorides for the prevention reversal of enamel white spot lesions during fixed orthodontic treatment included 3 RCTs two of which were at high risk of bias.
This review of the effectiveness of interventions delivered by mobile phones in improving adherence to oral hygiene advice for children and adolescents included just 2 small RCTs involving a total of 130 patients. The findings suggest that mobile phones are effective in improving adherence to oral hygiene advice in orthodontic patients.
This reviews of external root resorption (ERR) in patients receiving clear aligners treatment (CAT) with those being treated with fixed appliances included 11 observational studies. While the findings suggest ERR may be lower in patients treated with CAT the quality of the evidence is limited.
This review of the effects of micro-osteoperforation on the rate of tooth movement in patients undergoing orthodontic treatment included 6 RCTs. Although meta-analysis found a small statistical benefit in favour of micro-osteoperforation in the short term the clinical benefits particularly over the duration of a course of treatment remain unclear.
